I've met ONE man whose daughter's name was Kaede (sounds like Kai-day with the ai being phonetic like eye) and it's a very nice name.

One thing about anime/manga is you have to be careful not to confuse cartoon with reality because people sometimes make things up for cartoons and use rare names for effect, though some of the names are also fairly common in Japanese. Just be careful how much you base your perspective of Japanese society on manga.
